Playing with my Cousin

During the lockdown I got bored and as I lived with my cousin we started mucking about, which lead to us having sex. Of course we used condoms and everything seemed fine after the lockdown was over, but it wasn't. We either made some small mistake or one of the condoms split and we didn't notice. Either way Mary got pregnant and so we now have a baby girl we called Susanne. Who is healthy and so we still live together and still sleep together, might as well.
